POLE-TRAILER.

Application led October 31,

To all 'whom t may concern:

' take4 more in Be it known that I, OBRA E. BYRON, a citizen oftheUnited States, residing at Chicago, in the county of Cook and State ofIllinois, have invented a certain new and useful Improvement inPole-Trailers, of which the following is a full, clear, concise, andexact description, reference being had to the accompanying drawings,forming a part of this specification.

My invention relates to pole trailers and has for its object theprovision of an apparatus of this kind constructed in such a manner thatthe flexibility and automatic adjustability of its parts are such as toaccommodate for the peculiar uses to which the device is put. To thisend the device has means upon which the poles, such as telegraph polesand the likeJ may be placed, rollers being preferably provided tofacilif tate the reception of the poles. This pole receiving carriage isso mounted on the trailer that it may swing a certain predetermineddistance in either a horizontal plane or a vertical plane wherebythislpole carriage, within certain limitations, may practicallyuniversally adjust itself to the condition of its load.. The trailer isalso so arranged that proper accommodation is made for the warping ofthe body of the trailer when drawn over rough surfaces. I will explainone form which my invention may detail by referring to the accompanyingdrawings illustrating such em bodiment in which- Figure 1 is a top viewof my improved trailer;

Fig. 2 is a side view thereof;

Fig. 3 is an end view thereof;

Fig. 4 is a fragmentary top view of the pole carriage Fig. 5 is asectional view on line 5, 5 of Fig. 4; and

Fig. 6 is a sectional view on line 6, 6 of Fig. 1.

My improved device comprises a frame work consisting of the channels 10and 11 which at their right hand extremities (Fig. l1) are united by abolster 12 shown more clearly in Fig. 3. The channels 13 and 14 serve ascross pieces to make this frame work rigid, gusset plates as seen moreclearly from Figs. 1 and 2. A shaft 16 for carrying eye 1 whereby it maybe suitably drawn is mounted between Specification of Letters Patent.

' which the channels 10 and 11 form a being used in additionA PatentedSept. 13, 1921. 1918. serial No. 260,487.

the forward extremities 18 of the channels 10 and 11 being suitably heldin place by the bolts 19. Additional holes 20v are provided in the shaftso as to adjust its protruding extremity to any desired length. Thisshaft projects rearwardly through the bolster as seen more clearly fromFigs. l'. and 2 the shaft having a given play vertically within the holeprovided for its reception in the bolster 12. Suitable wheels 21 areprovided mounted upon the axle 22, this axle being united to the framework of part,

by the radius rods 23 and 24. The radius rods at their forwardextremities (Fig. 2)

are pivotally mounted as shown at 25 and are united to the rear axle attheir forward extremities by knuckle joints 26. 'Ihe bolster 12 isrigidly secured to the transversely mounted spring 27, the extremitiesof this spring being pivotally carried by the links 28 and 29. Theselinks 28 and 29 are pivotally held by the brackets 30 rigidly secured tothe axle 22. The brackets 30 are also provided on their top surface withcushioning springs 31 and 32 which coperate with shelves 33 rigidlysecured to the opposite ends of the bolster 12. As this bolster ismounted upon the sprin its central portion it will be seen t at thisbolster may tilt in*a vertical plane so that one or the other of theshelves 33 may come into contact with its corresponding spring 31 or 32.A pole carriage 34 is mounte upon the top of the bolster 12 and thispole carriage consists in part of the I-beams 35 to ether with uprights36 and 37. l

uitable angles 38 and 39 are mounted on top of the I-beam as moreclearly shown in Figs. 4 and 5 and support rollers 40. These rollersfacilitate putting the poles in position upon the said carriage. Smallchannels 41 are utilized to provide a irm bearing for the shaft 42 whichsupports the rollers. Straps 43 are provided so thatadditional uprightsmay be mounted in position 1f desired. The pole carriage is so arrangedthat it may swing in a' horizontal plane as more clearly indicated bydotted lines in Fig, 1, and the limit of this movement is governed bythe stops 44. In order to pivotally mount the I-beam in position it isprovided with a cast strap 45 having a central hollow bore, this strapbeing suitably held in place by rivets 46. The strap is pivotallymounted upon Q y weones in Fig. 6. A portion of the l-beam is brokenaway as shown at e8 so] as to permit swinging of this l-beam and hencethe pole carriage about the stud 47 as a pivot. From the descriptionthus tar given it will be seen that the pole carriage 34 may adjustitself into practically any position in accordance with its load. Fromwhat has been vdescribed the above mentioned advantages and others willvbe clearly apparent to those skilled in the art. Many modificationsmay, of course,

be made without departing from the spirit' of my invention however andwithin the scope of the appended claims.
